DUMPING-CART.

SPECIFICATION forming part of Letters Patent No. 740,252, dated September 29,V 1903. Application lecl February 25, 1903, Serial No. 145,034. (No model.)

and the like; and it has for its object to provide in a cart of the type referred to improved means for locking the cart-body to the frame to hold it in its normal pesition and which may be released quickly and with the exertion of but little power to cause the cart to dump its contents. l

To this end my invention consists in the features and'in the construction, combination, and arrangement of parts hereinafter described, and particularly pointed out in the claims following the description, reference being had to the accompanyingdraw'- ings, forming a part of this'specification, wherein-` 1 Figurek 1 is a view in side elevation of my improved dumping-cart, the body of the cart being shown in its dumping position in dotted lines. Fig. 2 is a rear end view thereof, the side doors or covers being shown partially open; and Fig. 3 is a bottom plan view.

Referring to the drawings, the numeralsl and 2, respectively, indicate the front and rear axles, and 3 the ground-wheels journaled thereon. The frame of the cart consists of two parallel metallic side bars 4:, each connected, respectively, at its front and rear ends to the fifth-wheel or bolster on the front axle and to the rear axle, said bars being arched in rear of the front axle to form asupport for the drivers seat 5 and also to permit of the front wheels being swung under the frame inY turning.

lThe numeral` 6 indicatesthe body of the cart, consisting of a rectangular vessel or boxlike structure permanently closed on its sides, front, and bottom and provided at its rear end with a gate or door 7, hinged at its upper end, as at 8, and at its lower end provided with a suitable fastening 9 of any ordinaryT or preferred construction for locking the gate or door in its closed position. The body 6 is provided with a peaked top 10- that is'to say, said top is of the shape of a truncated triangle in vertical cross-section, and its opposite inclined sides are closed by hinged doors or covers 11.

The bottom of the body of the cart is pivotally supported at a point slightly in rear of its center to the rear axle 2 and rests at its front end on the bars 1, forming the frame, the arrangement being such that the front end of the cart normally rests by gravity onV the frame, but will require but little power to swing it rearwardly about the axle to dump the cart.

The cart-body is detachably locked to the frame by the following mechanism: Arranged beneath the front edge of the bottom of the cart are two toggle-arms 12, that loosely pass through guides, eyes, or staples 13, attached to the bottom of the cart near its sides. The inner ends of said arms are pivoted to the forward end cfa sliding bar 14 by a single bolt or pivot-pin 14, and said sliding bar is arranged centrally and longitudinally beneath the forward portion of the bottom of the cart and passes loosely through a guide, eye, or staple 15, attached to the bottom of the cart, at or near the forward end of the latter. Journaled in suitable bearings on the bottom of the cart and extending from the center to one side of the latter is a rock-shaft 16, which is provided at its inner end with a crank 17, that is loosely connected to the rear end of the slide-bar or connecting-rod 14:, and said rock-shaftV 16 is provided at its outer end with a crank-handle 18 by means of which it may be turned in its bearings. The togglearms are of such length that when they are .in alinement with each other their outer ends will projectbeneath the side bars 4 of the frame and hold the forward end of the cartb'ody to its seat on the frame and prevent the cart from dumping. When it is desired to dump the cart, the body is released by raising the crank-handle 18 to a vertical position, thereby giving the rock-shaft a onequart'er turn. This movement of the rockshaft projects the connecting-rod 14 forward and retracts Athe toggle-arms from beneath the side bars 4, whereupon the cart-body can IOO be oscillated rearwardly upon the axle to dump its contents. When the cart-body is returned to its normal position-that is to say, when its forward end is again brought to rest upon the frameit is merely necessary to turn the crank-handle to a horizontal position, thereby retracting the connectingi'od and forcing the outer ends of the togglearms underneath the side bars 4 of the frame, and thus locking the cart-body to the frame.

Having described my invention, what I claim is` l. In a dumping-cart, the combination with a wheel-frame and a tilting cart-body pivotallj7 mounted on the rear axle thereof, of two arms arranged transversely of the bottom of the body, said arms loosely passing through guides fixed to said bottom and'adapted to project at their ends beyond the sides ofthe body and beneath the frame to hold the body of the cart locked to the frame, a reciprocatory rod loosely fitted in a guide on the bottom of the cart-body and movable longitudinally relatively to the latter, one end of said rod being pivotally connected to the inner adjacent ends of the said arms, and means for reciprocating the rod to turn said arms into and out of alinement, and thereby project the ends of the arms beneath the frame moese and retract them from thereunder, substan tially as and for the purpose specified.

2. In adumping-cart, the combination with a wheel-frame and a tilting cart-body pivotally mounted on the rear axle thereof, of two arms arranged transversely of the bottom of the body, said arms loosely passing through guides fixed to said bottom and adapted to project at their ends beyond the sides of the body and beneath the frame to hold the body of the cart locked to the frame, a reciprocatory rod loosely fitted in a guide on the bottom of the cart-body and movable longitudinally relatively to the'latt'er, one end of said -rod being pivotally connected to the inner FRANK C.
